高压无气喷涂工艺是目前国外广泛应用的一种涂装新工艺。国内也开始应用这项新工艺。高压无气喷涂的原理是利用气动、电动或其它动力使涂料在高压的作用下,通过特殊形状的喷嘴喷出,产生负压,剧烈膨胀,涂料则 High-pressure airless spraying process is widely applied abroad a new coating technology. China has also begun to apply this new technology. The principle of high pressure airless spraying is the use of pneumatic, electric or other power to paint under the action of high pressure, through the special shape of the nozzle spray, resulting in negative pressure, severe expansion, the paint is
